The irregular spiral galaxy NGC 5486 hangs against a background of dim, distant galaxies in this image from the NASA/ESA Hubble Space Telescope.
What are some skywatching highlights in March 2023?
Following their close approach in the sky on March 1, Venus and Jupiter go their separate ways. Venus climbs higher each evening, while Jupiter exists the morning sky at month's end. And those with binoculars of a small telescope can seek out... Read More
A “jellyfish galaxy” with trailing tentacles of stars hangs in inky blackness in this image from the NASA/ESA Hubble Space Telescope.
With the help of artificial intelligence and high-resolution satellite images, scientists mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests. Having an accurate tree carbon estimate is essential for... Read More
NASA's Hubble Space Telescope captured a series of photos of asteroid Dimorphos when it was deliberately hit by a 1,200-pound NASA spacecraft called DART on September 26, 2022.
NASA’s DART Data Validates Kinetic Impact as Planetary Defense Method
A new simulation shows how NASA’s Nancy Grace Roman Space Telescope will turn back the cosmic clock, unveiling the evolving universe in ways that have never been possible before.
An international team of scientists has uncovered new information about the remains of a star whose explosion was discovered 450 years ago. The results provided new clues about how the conditions in the shock waves created by titanic stellar explosions, called supernovae, accelerate particles to... Read More
A massive galaxy cluster in the constellation Cetus dominates the center of this image from the NASA/ESA Hubble Space Telescope.
The research uses archival NASA data to show that Venus may be losing heat from geologic activity in regions called coronae, possibly like early tectonic activity on Earth.
NASA’s MAVEN spacecraft entered safe mode on Feb. 16 after encountering an issue with its Inertial Measurement Unit, which measures the spacecraft rate of rotation for use in determining its pointing.
NASA and Advanced Thermal Batteries, Inc. are developing a high-temperature battery system to power a long-lived lander on the Venus surface.
